A Application tiled November 7, 1900. Serial No. 35,707. (No model.)

To @ZZ whom it may concern: Figs. 8 and 9 are respectively a face and a' Be it known that-I, FRANCIS VORBURGH longitudinal section of the windowstile after PHILLIPS, a citizen of the United States, reit has been operated uponin my machine. siding in Winterpark,in the county of Orange In said drawings, 10 represents a suitable 5 and State of Florida, have invented anew and standard supporting the machine, and 11 is 55 useful Improvement in Machines for Mortis- 'a stationary table rmounted thereon.

The 6o in windowcasings orframes. In myimproved tonguepl is.' located at one side of the longimachine I employ'a vertically-adjustable ro- -tudinal centerof the frame, and in order that tating bit or cutter, a support for the casingthe frame may be supported at the other side stile, movable laterally so as to position the of the center I provide screws 15, entering 'I5 stile iirst for the cutting of one of the morthe cross member 16.0f the frame from its un- 65 tises and then for the cutting ofthe other morder side and having their heads bearing upon tise, means for gaging such movement accuthe surface of the table.

Figure 1 isa side elevation, Fig. 2 is a plan, Upon its upper surface the support 14: is and Fig. 3 a transverse vertical section, of provided with an upstanding rib 24, adapted the invention. Fig. 4 is a perspective of the to lit the groove 25, with which the stile 26 45 stile-support. Fig. 5 is a detail elevation is provided, prior to its being placed in this 95 of the foot-lever for raising the cutter, showmachine, and in which groove the partinging the side opposite to that shown in Fig. 1. strip of the window-frame is afterward ini Fig. 6 is a vertical section showing the device serted. By means of the rib it will be seen for locking the support to the table. Fig. 7 that the stile will be positioned on the frame 5o is a detail section on the line 7 7 of Fig. 2. so that the mortises will come in correct polos sitions relative to each other and the partingstrip which comes between them. The stile is positioned longitudinally by abutting its end, as in Fig. 3, against the gage 27, which is supported in an upright piece 28, mounted upon a rod 29, horizontally and movably supported in the opening 30 in the verticallyslotted projection 31 of the frame. By the positioning devices now described (the rib 24 and the gage 27) the operator is enabled to correctly position the stile in the machine without any measurements whatever, and by means of the stops 18 and 19 he is also enabled to move the frame sidewise to correctly position t-he stile for the cutting of the second mortise.

During the cutting of the mortise the stile is moved longitudinally by a hand-lever 32,

pivoted to au arm 33, projecting from frame 14, the lever being connected to the rod 29 by a pivotal connection 34, so that the power of the lever is transmitted to the gage 27 and through such gage causes the sliding of the stile longitudinally along the rib 24. The extent of this movement depends, of course,

vupon the length of the mortise and is regulated by limiting the movements of the lever in any suitable way-as, for instance, by means of the plate 35, att-ached to projection 3l, and having its upper edge cut out to form two pairs of shoulders 36 37 and 38 39. The shoulders 36 37 are separated more widely and are located in a higher plane than shoulders 3S and 39 and prescribe the movements of the lever while the cutter is forming the flange-receiving portions 40 of the mortises, which are shown at 41, and the shoulders 38 39, giving a less range of movement, prescribe the movements of the lever during the cutting of the main opening of the mortises. After the cutting of each mortise, and also after the cutting of each Hangs-space, the lever is moved back to its next starting position, either against shoulder 36 or shoulder 38, and the stile is slid up against the gage 27 by hand, in readiness for the next operation. The lever 32 is shown at Figs. 2 and 4 in the position occupied by it at the completion of the cutting of the main opening and as against shoulder 39. At the completion of the routing of the flange-space it should stand against shoulder 33. As shown at Fig. 2 the carriage or frame 14 is shown as positioned for the operations on thc left-hand mortise, and to shift it for the cutting of the other mortise the locking device is released, and the frame is then shifted until the locking device encounters the stop 19. lVhen this has been done, the frame is again locked to the table, and the right hand mortise is cut.

'lhe bit orcutter is shown at 45. It is supported in the upper end of a vertical spindle 46, rotating in bearings 47 and 48 and driven by the pulley 49, belt 50, and pulley 5l, the latter on the drive-shaft The spindle is vertically movable in its said bearings and is supported upon the end of a foot-lever 53, pivoted at 54 and provided with regulating devices, as hereinafter stated. The lower end of thespindle, instead of beingjoined directly to the lever, is made spherical, as at 55, and inserted in the socket 56 in the block or bearing-piece 57, and the latter is forked, -so it may set over the lever and is pivoted to the lever` by the pivot 58. A cap 59 is 'preferably placed around the spindle and over the socket 56.

The spindle is intended to be raised to the work by the foot-lever, and as it is raised to 011e level for routing out the flan ge-spaces and to another level for cutting the main openings I provide the lever with the following devices: Above and below it are placed stops consisting of lugs 60 and G1 and set-screws 62 and 63 in said lugs. These prescribe the limits or range of movement both up and down permitted the lever; but in addition to these stationary stops I provide upon the lever itself a pivoted or swinging latch carrying a projection or stop so located normally that it will encounter the lower lug 6l when the lever is forced down and arrest the descent. This latch consists of amain body 64, pivoted centrally to the foot-lever 53 at 65, carrying at its lower end an adjustable stoppiece 66, adapted normally to engage said lug 61 and having its upper end 67 inclined over the treadle or foot-space of lever 53, as seen at Figs. 1 and 5, so that the operator may with the same foot whereby he depresses the lever 53 also swing the end 67 of the latch back, and thus carry the stop 6G so far forward that it will clear the lug 6l and allow the lever 53 to descend until it encounters the lower stop-screw 63. To move the spindle up forthe routing of the flange-spaces, the lever 53 is held depressed with the stop 66 resting upon lug 61; but when the main opening of the mortise is to be cut the operator pushes back the latch and depresses the lever until it meets the screw 63 and holds it there during the operation.

The stop 66 is made separate from the body of the latch, so it can be adjusted thereon. It is L-shaped, and an adjusting-screw GS is passed through its horizontal member and up against the bottom of the latch and a clamping-screw 69 passes through the elongated slot in the vertical member of the stop and into the latch and acts to clamp the stop firmly in its adjusted positions. By changing the position of the stop the depth of the cut in routing out the flange-spaces is regulated, as will be understood.

The device for locking the stile-supporting frame to the table of the machine is provided with a piece of leather or equivalent material 70 between the eccentric and the locking-pin. This acts to prevent any tendency of the eccentric to turn back and release the lock after it has been forced into acting position. It

IOO

IIO

also prevents the wear which Wouldoccnr if the eccentric camein direct contact With the pin.

The gage 27 is secured in its support 2S by meansof a set-screw 7l, and consequently can be set at any point desired, and the support 28 vis adjustably attached to the sliding rod 29 by a set-screw '72, so that all needed range of adjustment of the gage -is readily obtained.

Thatiportion Aof the bit which is entered within the spindle is tapered, as at 73, and provided with a screwp'lt at its lower point, and the socket in the spindle is also tapered and threaded at the bottom. struction the bit will always be drawn into the socket by the threads until its tapered sides bear snugly against the tapered Walls of the socketf While the cutter is operating there will be a tendency by the stile to jump upward, and

' to rest-rain this I employ a stop 75, bearing ment, it is clamped in position by the plate 77- needed, and While I' have set forth herein the f lightly on the top of the board over or in proximity to the cutter. This stop is made of Wood, soit will not injure the cutter should the latter comein contact with it, and it is supported in the stationary overhanging and unyielding arm 76. As the stop may need adjustand bolts 78. .It should not, of course, create -undue friction on the board or prevent it from moving.

The mode of operation ot' the machine has been already so fully explained in connectionwith the description of the partsand their functions that no specific description of it is downward movement, a movable stop arresting the lever When it has descended far enough for the cutting of the flange-spaces and re- .leasable by the operators foot, and a second stop arresting .the lever when it has descended far enough for the cutting of the pulleyopening, substantially as specified.
